Member Function Documentation

bool modm::gui::Widget::checkIntersection ( Widget * w )

inherited

Check if given Widget w overlaps on top. For widgets overlapping below this function also returns false.

void modm::gui::Widget::draw ( View * view )

inheritedinline

Interface for drawing widgets. Basically calls render(), but has some logic that needs to be executed before and after rendering a widget

bool modm::gui::Widget::handleInputEvent ( const InputEvent * ev )

inheritedvirtual

Handles InputEvents and calls activate/deactivate if event coordinates are within widgets dimensions. Returning true means, that the event was inside these dimensions, false if not.

Reimplemented in modm::gui::WidgetGroup.

virtual void modm::gui::Widget::setPosition ( const modm::glcd::Point & pos )

inheritedinlinevirtual

Set position of widget relative to its parent. Also updates the absolute position by looping through parents.

Reimplemented in modm::gui::WidgetGroup.

void modm::gui::Widget::updateIntersections ( WidgetContainer * widgets )

inherited

Clear old list of intersecting widgets and rebuild on the basis of the given widgets container.

virtual void modm::gui::Widget::updatePosition ( )

inheritedinlinevirtual

Updates the absolute position by looping through all parents and adding up their relative positions.

Reimplemented in modm::gui::WidgetGroup.
